ambari之hadoop的安装

• 大数据, 开源, 研发管理, 移动开发, 编程笔记

前期环境准备：

三台机器：192.168.1.25（1-3）；251-ambari_master；252-ambari_slare1；253-ambari_slare2

机器配置，系统环境

使用虚拟机，系统rhel6.6 ; centos6.5

所有机器都需要执行一下设置（我已经设置好了，可以看一下）：

1.打开最大文件数设置

[root@ambari_slare2 ~]# ulimit -Hn
10000

[root@ambari_slare2 ~]# ulimit -Sn
10000

补充：【

1. 修改/etc/security/limits.conf

通过 vi /etc/security/limits.conf修改其内容，在文件最后加入（数值也可以自己定义）：

* soft  nofile = 32768

* hard  nofile = 65536

2. 修改/etc/profile

通过vi /etc/profile修改，在最后加入以下内容

ulimit -n 32768

然后重新登录即可生效了。

说明：

其实只修改/etc/profile就可以生效了，但我还是建议把/etc/security/limits.conf也修改一下。

最后强调的是，你如果要使得修改对所有用户都生效，那么现在看来你只能重新编译Linux的内核才行。】

2. 修改hosts文件
[root@ambari_slare2 ~]# cat /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6

192.168.1.251 ambari_master
192.168.1.252 ambari_slare1
192.168.1.253 ambari_slare2

3. 设置selinux为disabled
[root@ambari_slare2 ~]# getenforce
Disabled

4. 关闭防火墙
[root@ambari_slare2 ~]# /etc/init.d/iptables status
iptables: Firewall is not running.

5. 开启ntpd
[root@ambari_slare2 ~]# /etc/init.d/ntpd status
ntpd (pid  5858) is running…

6. 设置环境变量jdk

[root@ambari_slare2 ~]# java -version
java version “1.7.0_79”
Java(TM) SE Runtime Environment (build 1.7.0_79-b15)
Java HotSpot(TM) 64-Bit Server VM (build 24.79-b02, mixed mode)

7. 配置ssh

[root@ambari_slare2 ~]# cat .ssh/authorized_keys
ssh-rsa AAAAB3NzaC1yc2EAAAABIwAAAQEAnxCVyAwzM743vB6KB4EVLDZ0+ydsmEtuMHD0ATar8zWqPDuBvGc4un5Fv1mIBCgOt3+GyWbDznACNlDzLkwRkxU8XhhTsRFHaWb9t9rH0N9dDEWbLqE1D70MY+oN7ZMVwDSooUESRx05Eg8szoDPY+JXHF8AWgigNUhesJkMVpshI+GNV/x3a9F2aRvTyk5QibMVcmNGYXdrIxzhX8VDWAWI1soy3vAorteHORzOdzWuPZm78MUYwTA1p7z1h7q4gfG3GIEThkCss72LE1m7mIwgTNeAlxWYXckxzhQC13pS1D2dWKLucQHhVqfU0QW5mPE0f/++oyx9trFr72Aaaw== root@ambari_slare2

8. yum -y groupinstall “Development tools”

9. yum -y install mysql*

10. yum -y install ruby* redhat-lsb* snappy*

制作ambari和hadoop本地源：

1. 创建本地源目录

选取一台服务器，安装http服务，安装完后会自动创建 /var/www/html 目录（我选的是251 ambari_master）
启动httpd 命令： service httpd start  || /etc/init.d/httpd start
                 chkconfig httpd on
创建两个目录：
mkdir  /var/www/html/ambari
mkdir  /var/www/html/hdp

2.安装createrepo（在这里需要强制安装，添加：–force –nodeps）

2.1 [root@ambari_master Packages]# rpm -ivh createrepo-0.9.9-22.el6.noarch.rpm –force –nodeps
warning: createrepo-0.9.9-22.el6.noarch.rpm: Header V3 RSA/SHA256 Signature, key ID fd431d51: NOKEY
Preparing…                ########################################### [100%]
   1:createrepo             ########################################### [100%]

2.2 [root@ambari_master hdp]# yum install python*

（输出结果太多，这里就不粘贴了，自己试试）

3.ambari本地源创建

解压HDP-UTILS-1.1.0.20-centos6.tar.gz 到目录 /var/www/html/ambari
命令：tar  zxvf  HDP-UTILS-1.1.0.20-centos6.tar.tar  -C  /var/www/html/ambari
把Updates-ambari-2.2.1.0目录拷贝到目录 /var/www/html/ambary

cd /var/www/html/ambari/HDP-UTILS-1.1.0.20/repos/centos6
mkdir Updates-ambari-2.2.1.0
cp -r /var/www/html/ambari/Updates-ambari-2.2.1.0/ambari /var/www/html/ambari/HDP-UTILS-1.1.0.20/repos/centos6/Updates-ambari-2.2.1.0

进入/var/www/html/ambari 目录，执行命令：createrepo  ./
ambari本地源制作完成

结果：

[root@ambari_master ambari]# createrepo ./
Spawning worker 0 with 50 pkgs
Workers Finished

Saving other metadata
Generating sqlite DBs
Sqlite DBs complete
[root@ambari_master ambari]# ls
HDP-UTILS-1.1.0.20  repodata  Updates-ambari-2.2.1.0

4. hadoop本地源创建

把HDP-2.4.0目录拷贝到目录 /var/www/html/hdp
进入/var/www/html/hdp 目录，执行命令：createrepo  ./  
hadoop本地源制作完成

结果：

[root@ambari_master ambari]# cd ../hdp/
[root@ambari_master hdp]# createrepo ./
Spawning worker 0 with 179 pkgs
Workers Finished
Gathering worker results

Saving Primary metadata

[root@ambari_master hdp]# ls
HDP-2.4.0  repodata

5. 系统光盘本地源创建

[root@ambari_master ambari]# mount -o loop /mnt/iso/rhel-server-6.6-x86_64-dvd.iso /mnt/cdrom/

[root@ambari_master ambari]# df -h
Filesystem            Size  Used Avail Use% Mounted on

[root@ambari_master ambari]#ls /mnt/iso/

检验：

[root@ambari_master yum.repos.d]# yum repolist

6. mysql 的配置

CREATE USER ‘ambari’@’%’ IDENTIFIED BY ‘ambari’;

GRANT ALL PRIVILEGES ON *.* TO ‘ambari’@’%’;

CREATE USER ‘ambari’@’localhost’ IDENTIFIED BY ‘ambari’;

GRANT ALL PRIVILEGES ON *.* TO ‘ambari’@’localhost’;

CREATE USER ‘ambari’@’ambari_master’ IDENTIFIED BY ‘ambari_master’;

GRANT ALL PRIVILEGES ON *.* TO ‘ambari’@’ambari_master’;

FLUSH PRIVILEGES;

CREATE DATABASE hive;

FLUSH PRIVILEGES;

CREATE DATABASE ambari;
FLUSH PRIVILEGES;

CREATE USER ‘hive’@’localhost’ IDENTIFIED BY ‘hive’;

GRANT ALL PRIVILEGES ON *.* TO ‘hive’@’localhost’;

CREATE USER ‘hive’@’%’ IDENTIFIED BY ‘hive’;

GRANT ALL PRIVILEGES ON *.* TO ‘hive’@’%’;

CREATE USER ‘hive’@’ambari_slave2’IDENTIFIED BY ‘hive’;

GRANT ALL PRIVILEGES ON *.* TO ‘hive’@’ambari_slave2’;

FLUSH PRIVILEGES;

CREATE USER ‘rangeradmin’@’%’ IDENTIFIED BY ‘rangeradmin’;

GRANT ALL PRIVILEGES ON *.* TO ‘rangeradmin’@’%’  with grant option;

CREATE USER ‘rangeradmin’@’localhost’ IDENTIFIED BY ‘rangeradmin’;

GRANT ALL PRIVILEGES ON *.* TO ‘rangeradmin’@’localhost’  with grant option;

CREATE USER ‘rangeradmin’@’ambari_master’ IDENTIFIED BY ‘rangeradmin’;

GRANT ALL PRIVILEGES ON *.* TO ‘rangeradmin’@’ambari_master’  with grant option;

FLUSH PRIVILEGES;

CREATE USER ‘root’@’%’ IDENTIFIED BY ‘root’;

GRANT ALL PRIVILEGES ON *.* TO ‘root’@’%’;

FLUSH PRIVILEGES;

7.查看yum源（检查，可以省略这步，我是为了后期安装简单所以放在这）

[root@slare2 ~]# ls /etc/yum.repos.d/
ambari.repo  HDP.repo  HDP-UTILS.repo  mnt.repo  redhat.repo  rhel-source.repo
[root@slare2 ~]# cat /etc/yum.repos.d/ambari.repo
[ambari-2.2.1.]
name=Ambari 2.2.1
baseurl=http://192.168.1.253/ambari/
gpgcheck=0
enabled=1

[HDP-UTILS-1.1.0.20]
name=Hortonworks Data Platform Utils Version – HDP-UTILS-1.1.0.20
baseurl=http://192.168.1.253/ambari/
gpgcheck=0
enabled=1
[root@slare2 ~]# cat /etc/yum.repos.d/HDP-UTILS.repo
[HDP-UTILS-1.1.0.20]
name=HDP-UTILS-1.1.0.20
baseurl=http://192.168.1.253/ambari

path=/
enabled=1
gpgcheck=0
[root@slare2 ~]# cat /etc/yum.repos.d/HDP.repo
[HDP-2.4]
name=HDP-2.4
baseurl=http://192.168.1.253/hdp

path=/
enabled=1
gpgcheck=0[root@slare2 ~]#

8. 配置安装ambari

主节点：

yum -y install ambari-server（这步会自动安装postgresql数据库，我使用的是mysql，所以停掉它）

service postgresql stop
chkconfig postgresql off

scp /var/lib/ambari-server/resources/Ambari-DDL-MySQL-CREATE.sql root@ambari_slave2:/root

mysql数据库节点：

use ambari;

source /root/Ambari-DDL-MySQL-CREATE.sql;

FLUSH PRIVILEGES;

ambari-server setup

ambari-server start

JAVA_HOME=/usr/local/jdk1.7.0_79

cd /usr/share/java
rm -rf  mysql-connector-java.jar
ln -s mysql-connector-java-5.1.17.jar  mysql-connector-java.jar

ambari-server setup –jdbc-db=mysql –jdbc-driver=/usr/share/java/mysql-connector-java.jar

cp /usr/share/java/mysql-connector-java-5.1.17.jar /var/lib/ambari-server/resources/mysql-jdbc-driver.jar

vim /var/lib/ambari-server/resources/stacks/HDP/2.4/repos/repoinfo.xml

  <os family=”redhat6″>
    <repo>
      <baseurl>http://192.168.1.253/hdp</baseurl>
      <repoid>HDP-2.4</repoid>
      <reponame>HDP</reponame>
    </repo>
    <repo>
      <baseurl>http://192.168.1.253/ambari</baseurl>
      <repoid>HDP-UTILS-1.1.0.20</repoid>
      <reponame>HDP-UTILS</reponame>
    </repo>
  </os>

然后就可以到web界面安装hadoop集群以及所需的组件了，在web安装过程中会出现问题，我在这就不一一细说了，其实终端或者log中都有提示，或者就有答案，不会的一些问题可以直接在网上找找，一般都有。

  1. echo never > /sys/kernel/mm/redhat_transparent_hugepage/defrag
    echo never > /sys/kernel/mm/redhat_transparent_hugepage/enabled
    echo never > /sys/kernel/mm/transparent_hugepage/enabled
    echo never > /sys/kernel/mm/transparent_hugepage/defrag

  2. 在web界面会到主节点的私钥，来识别子节点的机器：

    gpgcheck=0[root@ambari_master ~]# cat .ssh/id_rsa

  3. 后期会有补充：看完有问题可以直接联系我，QQ：1591345922
